LensPen sensor and lens cleaning tools : The LensPen Group introduced new digital camera cleaning tools at the Photokina 2012. From their five new lens, filter and display cleaning pens to an improved design on their sensor cleaning loupe. When you clean your digital SLR sensor using the LensPen SensorKlear system, you can see what you are cleaning while you clean. A new feature no other DSLR lens cleaning tool can offer. “Other lens cleaning systems use sprays and gels that can make a sticky mess that spreads all over the delicate parts of your digital camera. You can’t even watch what you are doing when you use them.” said Peter Meurrens, vice president of operations of the LensPen Group.
